Question 4864 Deck General

The correct answer is C) 1,914 foot-tons decrease. When 103.48 long tons of ballast is discharged from a full ballast tank 1P, the vertical moment will decrease. This is because the weight of the ballast (103.48 long tons) will be removed from the vessel, and the vertical center of gravity will shift upwards, resulting in a decrease in the overall vertical moment. The calculation to determine the change in vertical moment is: Weight of ballast discharged (103.48 long tons) x Vertical distance from keel to center of ballast tank 1P (18.5 feet) = 1,914 foot-tons decrease. The other options are incorrect because they do not accurately reflect the change in vertical moment based on the given information.
